RAM/ROM usage for MPC56xx

ZdenoQC — Wed, 08 Jul 2015 20:34:16 GMT

Hi there,

I'm using a MCP5605B in Codewarrior 10.4 and I want to know how much RAM/ROM I'm using. I was able to do that with S12/S08 by looking at the .map file like this one:

/---------------------------------------------------------

Summary of section sizes per section type:

READ_ONLY (R): 8985 (dec: 35205)

READ_WRITE (R/W): 961 (dec: 2401)

NO_INIT (N/I): 12C (dec: 300)

/---------------------------------------------------------

Is there a way to have those informations with the MPC56? I don't want to manually sum all the object size in the .map

Thanks

Sorry for the Qorivva linker does not support the feature to display the total ROM/RAM size used in application project.

I have contacted the developers for this feature request and will update this post for any news.

I got the reply from our developers as below:

Unfortunately, the PA map file doesn’t print a nice summary of segment sizes for the users like some the other CW targets.

That said, the ELF file generated by PA is consumable by standard Linux/Cygwin tools such as ‘size’ and ‘readelf’. I suggest these as a quick solution.

test1> size *.elf

text data bss dec hex filename

19896 1780 832 22508 57ec test1.elf
